Mechanical advantage Formula https://physicsteacher.in/2019/09/15/mechanical-advantage-formula/ Sun, 15 Sep 2019 08:52:20 +0000 https://physicsteacher.in/?p=3824 In this post we will talk about Mechanical advantage formula for different simple machines. Just to give you a quick headsup, Mechanical Advantage of a machine is the ratio of output force and the input force. In other words, it is the ratio of Load and Effort. Now to understand these in details we need
